ROAD

I Application nled March 1923. .Serial No. 626,408.

' ments in Road Markers, of which the following is a specification.

My invention relates to a machine for applying a ribbon or strip of paint to a road surface whereby to indicate the portion of the road to be used by vehicles moving in either direction.

It is one object of my invention to provide a movable device designed to carry a quantity of paint and equipped with suitable mechanism for applying the paint in the form of a bend upon the road surface over which it moves.

It is a further object of my invention to provide a vehicle of the character indicated provided with a guagefor positioning and guiding the paint applying. mechanism.

It is a still further object of my invention to provide suitable devices for feeding and applying the paint and steering the vehicle and to rovide controlling devices therefor.

Final y, it is an object of my invention to provide a device of the character indicated that will be simple in form, construc tion and o eration, and highly eflicient in its practica application.

In the drawing:

Figure 1 is a side elevation of the road marker.

Figure 2 is a rear elevation of the same.

Figure 3 is an enlarged detail of the feed mechanism.

Figure is an enlarged section on 4-4= of Figure 1. 1

eferring more particularly to the drawing, 1 indicates a tank provided with a filling opening at 2 and a cap therefor at 3, a aint strainer being inserted in said opening at 5.

The tank 1 is mounted on a shaft 6 provided with steering knuckles at 7 and wheels 8. To knuckles 7 are attached rearwardly extending arms 9 which are joined at their rear ends by a shaft 10 having a rack portion 11 in mesh with a pinion 12 which, in turn, is operated by a hand wheel 13 so that the revolution of wheel 13 in either direction will move the wheels 8 as desired.

At 19 are bars mounted upon the sides of p F. MAN'sthey run on either edge of the tank 1 and extending rearwardly thereof, a

shaft 15 being revolubly mounted therein and extending a distance both sides thereof as shown and. carrying rear wheels 16-16. Wheels 16 are adjustable longitudinally of ilslaft 15 by means of key 17 and set screws Bars 19 are extended and fitted with separable bearings 20 in which a shaft 21 revolves. 'On shaft 21 is fitted a sprocket 22 fitted with a chain 23 engaging a second sprocket 22 on stub. shaft 24 set in one bar 19, the sprocket 22 carrying a gear 25 meshing with a gear 26 on shaft 15. By means of this arrangement when the device moves forwardly the brush 26 mounted on the center of shaft 21 is revolved at the desired rate of speed in the direction indicated by the arrow.

In the bottom of the rearend of tank 1 is provided a discharge opening 27 regulated by a gate 28 operated by a screw 29. At 30 is a chute receiving paint from opening 27 and discharging at a point adjacent to the road surface and close to the brush 26 as shown. r

In the present case the tank 1 is fitted with a handle 31 and a dra in'valve at 32.

This device is particularly useful for marking a center line on asphalt pavements of a given uniform width such as are commonly used in "building western hi hways,

whereby the width of pavement to used by oppositely moving traffic is clearly designated.

Supposing the tank 1 is filled with amt,-

preferably white, the device is move into position in the center of the pavement and wheels 16 are adjusted on shaft 15 so that avement. The ate 28,, is now opened a distance to permit the paint to run down chute 30 to brush 26, and the vehicle is moved forward. The brush 26 now applies the paint to the pavement in a band the width of which is determined by the width of the brush used.

Since the brush rotates against the direction of movement of the vehicle no surplus paint is left on the pavement, the supply of paint to chute 30- being just SlllfiClGIlt to keep the brush wet.

It is to be understood, of course, that while I have herein shown and described one specific embodiment of my invention changes in form, construction and method of operation may be made within the scope opposite sides thereof, a shaft journaled in the bars and having its ends extending late-rally beyond the tank, paint-applying means driven by the shaft, and gage wheels adjust-ably mounted on the shaft.

2. A marker comprising a wheeled tank,

rearwardly extending bars secured to the opposite sides thereof, a shaft journaled in the bars and having its ends extending laterally beyond the tank, gage Wheels on the shaft, a second shaft journaled in the side bars, a brush on the second shaft, and means for driving the second shaft from the first shaftto rotate the brush against 20 the direction of travel.

3. A marker comprising a Wheeled tank, rearwardly extending bars secured to the opposite sides thereof, a shaft journaled in the bars and having its ends extending laterally beyond the tank, gage wheels on the shaft, and a brush journaled in the side bars and'driven from the shaft, to apply the coating material from the tank.
